2  Bitcoin / Electrum / Unable to run Zclassis Electrum wallet, need advice. on: February 18, 2018, 03:42:49 PM
Hello gentelmen, Smiley

I've downloaded Zclassis Electrum wallet from github  (, Linux version  (Z!1.0.3.tar.gz  archive file), unarchived it, read  README file,  that says:

If you downloaded the official package (tar.gz), you can run
Electrum from its root directory, without installing it on your
system; all the python dependencies are included in the 'packages'
directory. To run Electrum from its root directory, just do::


When I run ./electrum, I get error:

ImportError: No module named 'pyblake2'

I searched for pyblake2 (Python module), and istalled it .   Ans I still get the same error:   No module named 'pyblake2'

Any idea, please??  
3  Alternate cryptocurrencies / Mining (Altcoins) / Warning about INNOSILICON on: January 30, 2018, 09:55:51 PM
Here is an ugly and nasty story of INNOSILICON.    

It happened a few years ago.  Innosilicon appeared to be a very bad partner for a BITMINE AG company who produced their miners, but went bankrupt due to Innosilicon unfair behaviour.  

BITMINE AG  paid 8M CHF to Innosilicon for development and production of chips that turned out to be a JUNK.

This story also points to the fact that Innosilicon produces chips of a poor quality.  This explains why their last A5 miner are so bad.  It starts burning, and Inno issued already a few software patches trying to fix the issue.

Open letter from the former BITMINE AG management

Innosilicon. The company that we engaged for the development of our A1 CoinCraft chip ended up in being BITMINE’s biggest failure. We engaged this company with a regular contract and entitled them to develop our 28nm ASIC based on our know-how and instructions, along with the full turnkey process of creating the mask, wafers and IC packaging. We had signed a contract that was expecting to guarantee us a one year exclusivity on the chip, however at a later stage we received proof that Innosilicon was plainly violating the contract from day zero and selling our own A1 chips to whoever inquired them directly. Once we pointed this out, they simply stopped answering our enquiries and disappeared, putting us in obvious panic because we had an extremely tight schedule and obligation to deliver the miners on time and they knew that perfectly. So, once they knew how attractive the market we were into was, they forced us into signing an amendment to the contract where we allowed them to sell the A1 chips to third parties. Additionally, they even forced us to write formal excuse letters for the “false” accusations under the threat that if we hadn’t signed them, they would just delay the supply of the A1 chips so long that they would be worthless.
Once the first production lot of chips, with a delay of nearly two months and a performance 50% worse than promised was delivered to us, the issue of “yield” popped up. Innosilicon repeatedly delivered us broken chips or “junk grade” ones as part of the purchased (and paid for) lots, forcing us to place ever bigger and bigger orders in order to fulfill our customers’ orders and eventually draining out most of the company’s money. Out of all the ordered chips, a huge part of them were simply not working and could only be thrown away in the garbage bin. Here you will see for yourself the pictures of the piles of tens of thousands of worthless junk grade chips still sealed in their original packages. When asked about clarifications, they claimed this was “normal production yield” but failed to provide any relevant document that could certify it. It is also worth mentioning that while we were struggling with thousands of junk chips, the A-grade ones could at all time be purchased in Hong Kong directly from their Chinese resellers, at some point even at lower prices than what we ourselves paid for.
At the end of this horrific experience, we had paid to Innosilicon in 2013 and 2014 a total of more than 8 million CHF but received only a small amount of usable A1 chips, causing us a huge financial loss. Therefore, we enquired two different lawyers in order to evaluate legal actions against them, but ended up with answers that more or less said that the chances of getting our rights respected from a Chinese court against a local Chinese company were close to zero. We only later found out this is a common practice from Chinese companies, regardless of the written agreements you make with them.
4  Bitcoin / Hardware wallets / ASICVAULT: The Most Secure Cryptocurrency Hardware Wallet on: January 08, 2018, 12:40:06 AM
There is a new very secure hardware wallet launching   -  surpassing Trezor and Leger, as producers claim.  They say it provides 1000 times(!) better security than any other hardware wallet/

For me it look very nice, especially in aluminium-titanium case, and I would like to buy it (though it is rather expensive - around 200 Euro) :

Short description from the website:        AsicVault is a next generation storage device specifically designed for cryptocurrencies. Developed by a company in Estonia, it provides the best security features. Aside from providing cutting edge cryptocurrency software wallet security, this device is fabricated to provide the best physical security as well.

AsicVault’s custom chip equipped with “crypto accelerators” provides 1000 times better security than any other hardware wallet. Its custom chip is composed of two physically isolated RISC-V processors. The device uses all round “anti-tampering technologies” to make it physically secure. This feature essentially makes this device more of a vault than a hardware wallet.

With no batteries, this device uses Supercapacitor technology for energy. Moreover, a number of embedded self-destruct modes enhance its security reliability. AsicVault also provides complete encryption for your computer hard drives. All the encryption algorithms are run on the device thus never exposing keys to your computers. The device controls can easily be accessed through a user friendly interface. A touch screen display on top of the device provides a smooth user experience.


Here is video from exhibition:


For me is unclear why there is not really much information about this device in independent media.   If this device is 1000 times more secure than other devices, why media does not cover it?    There are some articles on the net which seems to be promoted, though.

Can it happen that producer will be able to maybe steal money from it, remotely ?  

What do you think about it?    

5  Economy / Computer hardware / 8 Bitmain APW3++ for sale - $1300 - free US shipping -- NEW PRICE ! on: December 02, 2017, 09:58:04 PM
Hello everybody,  

I want to sell in one whole lot only eight ( 8 ) units of new APW3++ PSUs,  for $1500,  free shipping within US.   (for international shipping add $200).

It happened I had ordered surplus miners from Bitmain, which I don't need (can show the order's screenshot if necessary).  They arrived a week ago, and I did not unpack them.

This makes around $150 price per PSU, if you count the shipping cost from China.

They are located in Washington state, shipping within 5-7 days.

I am ok with BTC/LTC/ETH/DASH.     You may use any escrow listed in bitcointalk, at your expense  Smiley      Or don't use it, counting on references in my trust section  Wink

7  Economy / Scam Accusations / Wallet-Monero Is Attempting to Steal Your XMR on: November 24, 2017, 09:10:01 AM

The Wallet-Monero website also claims that all rights are reserved by Monero. That is a very big red flag, considering that the Monero team has not officially endorsed this wallet nor are they involved in its development or maintenance.

The domain name was registered about a week ago, which further indicates this platform should not be trusted.

People looking for a proper Monero wallet will need to do their homework and avoid the multiple scams floating around on the Internet.
8  Economy / Scam Accusations / BE AWARE -- "Electron Gold" steals private keys. on: November 23, 2017, 07:56:48 PM
There are two major forks of Bitcoin, one of which is legit and one of which is basically a scam.

Bitcoin Cash is the first and forked in mid-October.

Bitcoin Gold is the second and forked... at some point. It's not actually hugely clear.

Anyways, Electron Gold is a fork of Electrum, which is a lightweight Bitcoin wallet. The idea is that you would load your Bitcoin private keys into Electron Gold to "split" your Bitcoin and Bitcoin Gold, and gain access to both.

However, it looks like Electron Gold also sends your private keys to a third party, allowing them to steal both your BTC and BTG.
9  Economy / Speculation / Bitcoin for $1 Million !!! In ten years? on: November 22, 2017, 11:07:56 PM
Chart from 2014, when Bitcoin was $300, predicted price of $10k for today — Nov 22nd, 2017.  

We're at $8,200.  (If we add Bitcoin Cash and Gold prices, we'll get close to $10k).

Next milestone on chart: $100k in summer 2021.   And next: $1M in 2027.

10  Economy / Scam Accusations / Fishing attempt offering Bitcoin Gold - from on: November 15, 2017, 05:33:14 PM

If you point on the Blockchain (FROM field) - you will see this email address:

11  Economy / Scam Accusations / ToTheMoon (TMT) ICO is a Scam on: October 07, 2017, 09:34:28 PM
ToTheMoon (TMT) ICO is a Scam

Published 2 days ago on October 6, 2017 By Sam Bourgi has learned through one of its readers that ToTheMoon (TMT) “professional mining” is a scam. The distressed reader phoned the local power cooperative that supports the land where TMT mining pods are supposedly located. Not only does the power company not serve TMT, it hasn’t even heard of it. In a town of 350 people, that simply doesn’t add up.

When our reader questioned TMT, it quickly banned him from both Slack and Twitter.

“My only goal at this point is to prevent others from losing their money,” he told Jonas Borchgrevink, Director of, via email.

Upon further investigation, TMT is a nearly verbatim ripoff of Giga Watt, an East Wenatchee, Washington company. has since contacted Giga Watt informing them that their website content has been used by scammers.

ToTheMoon: Total B.S.

There are few indications that TMT is up to no good. The company operates a clean website with a downloadable link to a 23-page whitepaper describing its upcoming token sale. The supposed Ethereum-backed token was said to have a total supply of 51.75 million.

TMT’s website claims the following:

“ToTheMoon provides turnkey mining services and custom packages tailored to clients’ needs: full range of mining services from equipment sales, maintenance and repair to private blockchain servicing.”

Now compare this with Giga Watt:

“Turnkey mining services or custom packages tailored to your needs: full range of mining services from equipment sales, maintenance and repair to private blockchain servicing.”

TMT was even listed on a number of ICO websites and had already raised significant funds. The scam should remind investors to carefully evaluate every ICO they come across. As the ICO market continues to grow, scammers are going to try to steal their piece of the pie.

To its credit, the U.S. Securities and Exchange Commission (SEC) has warned investors about potential ICO scams, especially “pump and dump” schemes. Very few expected the type of sleaziness that the makers of TMT tried to pull off.
